Abstract: A method for reducing the content of nitrosamines (e.g., N′-Nitrosonornicotine, 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone, N′-Nitrosoanatabine, and N′-Nitrosoanabasine) in tobacco is provided. In one embodiment, the method includes combining tobacco with a solvent (e.g., water and/or other compounds) to form a soluble portion. The soluble portion contains an initial total level of tobacco-specific nitrosamines per gram of the soluble portion. The soluble portion is contacted with a nitrosamine-reducing material such that the resulting weight percentage of the tobacco-specific nitrosamines per gram of said soluble portion is at least about 20% less than the initial total level of the tobacco-specific nitrosamines per gram of the soluble portion.

Abstract: The invention concerns cigarette spotting.To reduce or prevent cigarette paper spotting, the cigarette is provided with an inner wrapper placed between the tobacco column and the external envelope, this inner wrapper being a paper made of cellulose fibers, with a basis weight at the utmost equal to 30 g/m.sup.2, presenting pores made during paper manufacture, or perforations made after manufacture in such a way that the air permeability is at leaste 500 Coresta units.This invention applies to all cigarettes and similar smoking products.

Abstract: Aromatized reconstituted tobacco is prepared from tobacco particles by extracting the particles with water to form an extract containing between 5 and 20 g/l of sugar, fermenting the extract with a yeast of the genera kluyveromyces, saccharomyces or candida, forming sheets from the extracted particles, and incorporating the fermented extract into those sheets.
